GENERAL DESCRIPTION
The ADR293 is a low noise, micropower precision voltage
reference that utilizes an XFET(eXtra implanted junction
FET) reference circuit. The new XFET architecture offers sig-
nificant performance improvements over traditional bandgap
and Zener-based references. Improvements include: one quarter
the voltage noise output of bandgap references operating at the
same current, very low and ultralinear temperature drift, low
thermal hysteresis and excellent long-term stability.
The ADR293 is a series voltage reference providing stable and
accurate output voltage from a 6.0 V supply. Quiescent current
is only 15 µA max, making this device ideal for battery powered
instrumentation. Three electrical grades are available offering
initial output accuracy of ± 3 mV, ± 6 mV, and ± 10 mV. Tem-
perature coefficients for the three grades are 8 ppm/°C, 15 ppm/°C
and 25 ppm/°C max. Line regulation and load regulation are typi-
cally 30 ppm/V and 30 ppm/mA, maintaining the reference’s over-
all high performance.
The ADR293 is specified over the extended industrial tempera-
ture range of –40°C to +125°C. This device is available in the
8-lead SOIC, 8-lead TSSOP and the TO-92 package.
